-+ * @sprom: The SPROM data structure to register.
-+ *
-+ * With this function the architecture implementation may register a fallback
-+ * SPROM data structure. The fallback is only used for PCI based SSB devices,
-+ * where no valid SPROM can be found in the shadow registers.
-+ *
-+ * This function is useful for weird architectures that have a half-assed SSB device
-+ * hardwired to their PCI bus.
-+ *
-+ * Note that it does only work with PCI attached SSB devices. PCMCIA devices currently
-+ * don't use this fallback.
-+ * Architectures must provide the SPROM for native SSB devices anyway,
-+ * so the fallback also isn't used for native devices.
-+ *
-+ * This function is available for architecture code, only. So it is not exported.
